We are pursuing new possibilities for press technology,
toward the creation of high-performance transmission parts.
Precision press technology that improves upon casting and forging methods
Replacing conventional methods of casting, forging and cutting with a press method through the precision press technology has brought significant cost reduction caused by productivity improvement and material cost reduction

With our integrated capabilities from development to production,
we are on the way to becoming the global leader in pressed transmission parts.
Unipres produces transmission parts with precision, strength and complexity thanks to pressing. We have built an integrated system for product development, production method development, quality assurance, and production. This enables us to provide high-performance transmission parts such as multi-stage automatic transmission and continuously variable transmission (CVT) parts.

The challenge of a high-efficiency torque converter for an eco-society
Unipres entered the torque converter business in 2008 and is involved in every aspect from development and design to manufacturing. As a device for automatic power transmission, a torque converter with higher transfer efficiency results in improved fuel economy. Employing the ultimate in precision press technology, we manufacture parts in house and carry out new development to achieve light weight and high efficiency, greatly reducing fuel use.

Torque converter parts
Clutch pack

Multiplate clutch for shift of automatic transmission. It requires strength and performance of the parts such as clutch drums and plates along with design technology that keeps them compact.
Carrier pack

High-precision planetary gear mechanism for speed change of the automatic transmission. It is manufactured by a combination of micron-scale processing and electron beam welding for the assembly.
The advance of near net shaping at the frontiers of press processing
Our ideal is to produce the most complex of shapes by pressing. Near net shaping is taking us closer to that goal. UFP (Unipres Fine Press) precision press technology, with its techniques for forming geared parts and plate thickness control, is able to realize high press precision to minimize the need for cutting, saving production time and reducing material cost.
Our production efficiency surpasses that of conventional forging and casting approaches.
